SACK-LIN ING MACHINE.

Specification of Letters Patent.

Patented June 14, 1921.

Application led April 20, 1920. Serial No. 375,416.

This invention relates to a machine torV lining sacks and its object is to place one sack within another. j Y

It will be understood by those skilled in the art that in the handling of sugar and some other commodities that jute bags are used, which are provided with an inner liner of a closer fabric. as for'example, in the case of sugar, a jute bag is lined with a fine cotton sack.

In the present invention the jute bags are placed upon a support and the cotton bag'is placed upon anothersupport whereupon suitable arms push the cottonr bag into the jute bag and project the corners Vof the cotton bag into the corners of the jute bag and then pull the two bags off their supports and push them toward a pair of rollers, which rollers pull the bags off the apparatus for placing the cotton bag within the4 jute bag and remove them to a suitable place of storage.

Other objects of the invention will appear as the description proceeds.

An. embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.

plete apparatus.

F ig. 2 is a front elevation of the completey apparatus with the table for supporting the liner removed for purposes of illustration.

Fig. 3 is a perspective view of the two bags in position for the liner to be'mserted within the jute bag. r

The apparatus comprises a pair oi' vertically extending bars 1 and 2 which are connected at their upper ends to suitable members 3 and 4 to form the ceiling joists of the plant in which the machine is installed and braces 5 and 6 are used to connect the members 1l and 2 with said joists to give them additional stiffness.

At the lower ends, the bars 1V and 2 are tional cross bars `movable in the slot between the shaft 41.V

connected to a pair of braces 8 and 9 on one side and to braces 10 and 11 on the other side. Connecting the members 1 and 2 are cross bars 13 and 14 and two guides 15 andy 16 extend from the lower cross bar 13 to the ceiling joists 17 and 18 and addi- 19 to 24 inclusive connecting with the bars 1 and 2, serve to hold the guides l5 and 16 in their proper position.

The cross arm 13 supports two large balls 25 and 26 and a stift7 spring 27 carries a similar large ball 28 which stands in front of the center of the machine. Vertically guides 15 and 16 is a slide 29, having two arms 30 Vand 31 pivotally mounted thereon, which large wheel 40 on a shaft 41, journaled in Y bearings 42 and 43, which hang down from a suitable frame 44 attached to the ceiling of the room in which the machine is installed.

A pulley 45 serves to supply power to the The wheel 40 is pivotally connected to a pitman 46 which has its upper end connected to the slide 29 so that as the wheel 40 rotates, the slide 29 and the arms 30 and 31 are raised and'lowered.

Attached to the braces 8 and 10 respectively are two stiff spiral springs 46 and 47, which support large knobs 48 and 49. Platforms 50 and 51 are provided for the operators and a table 52 is provided for the support oi the liner sack, while it is being pushed into the outside sack.

The table 52 is supported upon suitable posts 53 and 54 and the platforms 50 and 51 are supported upon suitable posts 55 to conveyer belt will drive the roller 66 Yand thereby drive the roller 65 to pull the sacks off7 the sack holding apparatus and deliver them tothe conveyer to be carried to a place of storage. l

The operation of the machine is as follows: The operators stand on the platforms 50 and 51 and as the arms 30 and 31 riseV` and fall continuously the operator on the platform 50 will place a jute sack on the knobs 48 and 49 the springs being stiff enough to hold the sack in .place with some tension at the same time the operator en the platform 5l will place the liner sack onv the two knobs 25 and 26 and will spring the knob 28 into the mouth of the sack so that it will assume the position shown in Fig. 3.

After the sack has been placed as shownv Y of the' sack they will continue to descend and pull the sack off` the knobs 18 and L19 and pull the liner sack off its supporting knobs and push the two sacks between the two rollers 65 and 66. Said rollers will then vpull the sack off the arms and the endless conveyer 65 will discharge the two sacks to the right F ig. 1 to a suitable place of storage.

In order to prevent the arms 30 and 31 from pulling the liner sack on the edge of the outer sack and pulling the latter off its supporting knobs, a rod 7 O is connected with the two vertical members 1 and 2 and extends across the front of the machine just below the plane of the supporting knobs for the liner and above the plane of the knobs 48 and 19 for supporting the outer sack.

The result of this is that the liner is pulled off the rod of the support until the liner is pushed far enough into the outer sack to insure its proper disposition therein.

What we claim is as follows, but various modifications may be made in the construe tion shown in the drawings and above particularly described form. within the purview of our invention: v

1. A machine for lining sacks comprising a suitable frame, a pair of sack supports carried thereby, supports for a second sack at a distance from the rst supports and a pair of reciprocating arms adapted to push the second sack into the rst sack.

2. A sack lining machine comprising a ports, a pair of reciprocating arms adapted to push the 'second sack into the first sack. means to spread said arms to push the corners of the second sack into the corners of l the first sack and means to pull the two sacks off the supports.

4. A sack lining machine comprising a supporting frame work, a pair of spring supports carried thereby, other supports for a second sack, means t0 push the second sack into the first sack, a pair of rollers to pull the two sacks offl their supports andan endless conveyer for delivering the sacks to a suitable place of storage when passed through the pair of rollers.

5. A sack lining machine comprising a supporting frame work, a pair of spring sack supports carried thereby, other supports for a second sack above the first supports, a pair of reciprocating arms adapted to push the second sack into the first sack, means to spread said arms topush the corners of the second sack into the corners of the first sack, a pair of rollers to pull the two sacks'off the arms and supports therefor and an endless conveyer to discharge the sacks to a suitable place of storage when pulled off the sack-supports. p f f 6. A sack lining machine comprising a supporting frame work, a pair of spring sack supports carried thereby, fixed supports for a second sack, a spring support in the plane of the second supports, Va pair of reciprocating arms adapted to push the second sack into the first sack, means to spread the arms to push the corners of the second sackV into the corners of the first sack, a pair of rollers between which the sacks are pushed on the end of the stroke of the reciprocating arms and an endless belt in contact with one of said rollers to discharge the sacks to a suitable place of storage.

In testimony whereof We have hereunto set our hands this 8th day of April, A. D.
